由于在国内访问Flutter有时可能会受到限制，Flutter官方为中国开发者搭建了临时镜像，大家可以将如下环境变量添加到到用户环境变量中：

注意： 此镜像为临时镜像，并不能保证一直可用，读者可以参考https://flutter.dev/community/china 以获得有关镜像服务器的最新动态。

set PUB_HOSTED_URL=https://pub.flutter-io.cn
set FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

再次执行

安装Android Studio和Android 工具链

下载页面： https://developer.android.com/studio/index.html

注意关闭代理。开启代理反而下载不了......

Unable to locate Android SDK. //原因 找不到安装 sdk

flutter config --android-sdk E:\DevKits\Android\Sdk //设置安卓sdk位置

flutter doctor --android-licenses //Android 同意使用协议

什么 java jdk版本太高问题。原来安装java jdk 19，改到java jdk11 就好了。记录一下

巴拉拉巴拉，反正安装过程一堆错误就没记录，真的是烦死人。

反正就是有什么错误就去搜索就行了，一步一步解决总能解决。

最后还是顺利的跑通了demo，跨出第一步就好，接下来慢慢看文档完事~
